I saw one on NASA's website, but it's only a ISIS Cube file, does Terragen recognize that?
			
			
			
				Have you checked these softwares out?
			
			
			
				Never mind, there is an entire process of processing the cube data. I found an alternative source. So
			
			
			
				Terragen should be able to read the LOLA data natively, I believe:

				Thanks. So do I just load the cube file as DEM data?
			
			
			
				You should try that, yeah. If it doesn't work here's a source that has data in GeoTIFF which Terragen can definitely read:
